Photo taken in Gotland, Sweden on July 09.

Is it vernale or festivum?

Thanks
Johan

I am not an expert, but I think this one is clearly vernale: I can see dark base to the femora and no yellow spot on the katepisternum. Besides, the shape of the abdominal yellow bands is closer to that of vernale too.

Hope somebody can confirm this :)
